Hi, I created a custom compiler for ExtJS. I'm going to be using it on several projects, and so I'll try to keep it up to date. It has a definition file for ExtJS 5 and the compiler will infers more of the ExtJs conventions and thus helps out more with
intelisense when writing code. For example you can tell the compiler to infer a configuration interface that you can use to pass to the constructor, and then you get help when calling the constructor. Since the typescript language service can be changed for
visual studio by changing the typescriptServices.js the changes are available right from Visual Studio.
